Was cannabis to blame?

Some people believe cannabis isn't a harmful drug. Within the Conservative party, unlike Labour, we are prepared to debate these issues. I am still not convinced that the Government's decision to downgrade cannabis was the right one.

This view was confirmed today with the news that the police believe the prime suspect in the stabbing of Abigail Witchalls was Richard Cazaly, who later killed himself.

The police note that, "Mr Cazaly became psychotic and violent as a result of long-term abuse of drugs and the alcohol he had consumed on the day of the stabbing".

The question for me is what effect is long term cannabis use having on people, and isn't this something we really need to be concerned about?
